Abstract: Provided is a charging system of a vertical rotary type parking apparatus, and more particularly, to a charging system of a vertical rotary type parking apparatus in which linear busbars through which power is supplied are mounted on the left and right frames of the parking apparatus, and a collector that is slidably coupled with the busbars for receiving electricity and a charger are mounted in each pallet on which a vehicle is loaded, thereby charging electric vehicles during parking.

Abstract: The present invention relates to a method and a kit for diagnosis of semen quality (motility and concentration) through observation of color change visible with the naked eye in a solution combining methylene blue and sperm. The invention comprises a method for semen diagnosis using color coding (with a standard color table) charting the various colors the semen may change into, and a diagnostic it for testing semen using said method. When combined with methylene blue, healthier and more active sperm fades the original blue color more rapidly due to respiration activity by the sperm, which allows for semen quality evaluation. The above principle are adapted to kit from inside a tube which encases a methylene blue solution into which sample semen is introduced for easy evaluation.

Abstract: Provided is a simple vertical rotary parking system by which noise generated due to a circulation of a sustain chain is greatly reduced. In the vertical rotary parking system, chain guide rails each forming a vertically long endless track are formed on a frame. A suspension chain for pulling hangers with palettes on which vehicles are loaded is combined between the chain guide rails such as to be rotated. A driving motor is fixed to the frame. An annular rotating body has an inner circumference on which an inscribed gear is formed, and includes at least two pull blocks formed opposite to each other. Hanger support plates for pulling the hangers are fixed to the suspension chain and each constituted with a pair of dogs, between which the pull block enters so that the suspension chain is pulled. In the vertical rotary parking system, the suspension chain circulates while a hanger support plate is being pulled by the pulling block.
